Synapse structure - Study guides, Class notes & Summaries

Acytelcholine - Answer--Excitatory; increases muscle contraction and depresses parasympathetic system. Associated with learning, memory, and attention → too little leads to Alzheimer's -Basal forebrain→ contains nucleus basalis -Targeted by Nicotine and succinylcholine Adaptation - Answer-The slowing of action potential firing overtime -Occurs in K+ Hyperpolarization Channels Agonist vs. Antagonist - Answer-Agonist: Chemical binds to the same site as an endogenous substance (e.g., ne...

the key structural components of neurons are (Ans- cell body, dendrites, axon Paul Broca's and Carl Wernicke's research provided early evidence for what? (Ans- localization of function a synapse is (Ans- space between neurons action potentials occur in the (Ans- axon When recording from a single neuron, stimulus intensity is represented in a single neuron by the (Ans- firing rate of the action potentials. Which of the following statements best describes how neurons com...

1. synthesis: - neurotransmitter manufactured in cell 2. storage: - neurotransmitter stored in vesicles for protection 3. release - action potential arriving at axon terminal will cause vesicles to move to membrane and release neurotransmitter into the synapse 4 key elements for electrical communication in neurons: - sodium, chloride, potassium, calcium - become charged when dissolved (NA+, K+, Cl-, Ca^2+) 4. receptor activation - neurotransmitters in the synapse can freely move about it. ...

CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...
